Custom tags let you attach your own labels to each comic, beyond the standard categories (condition, price, CGC, signed). Labels like christmas-gift-2024, attic-box-right, to-reread, loaned-julien or masters-thesis become filtering dimensions unique to each collector. My Comics Collection shipped this feature on June 4, 2026, with autocomplete on tags you've already entered, MySQL persistence, multi-tag filtering with AND logic, and bulk application through the bulk-edit modal. Fifty tags maximum per comic, thirty characters per tag.
A comic collection organized solely around the dimensions standardized by the apps on the market — conservation condition, purchase price, CGC grade, creator signature, wishlist status, duplicate status — hits its limits fast. These categories cover basic inventory needs, but they ignore the most personal dimension of a collection: the way each collector mentally structures their holdings. A comic might be "the one my grandmother gave me for my twelfth birthday," "the one I have to return to Maxime," "the one in the top-right box in the garage," "the one I wanted to reread for September's book club," or "the one that inspired my master's thesis." None of that information naturally fits into a "condition" or "purchase price" field. Yet these are precisely the invisible labels that define a collection's singularity and determine how quickly its owner can master it. Custom tags, added to My Comics Collection on June 4, 2026, surface that dimension explicitly and make it filterable.
Why standard categories aren't enough
The eleven standard filters offered by My Comics Collection (All, Ordered, CGC, Variant, Signed, Loaned, Read, Key issue, Wishlist, Annual, Duplicate) cover the universal needs every serious collector shares. They're sufficient as long as the collection stays within a neutral inventory logic. The moment a collector introduces their own organizing logics — sentimental, thematic, geographic, transactional — these predefined filters fall short. Four examples illustrate that ceiling.
First example: physical location. A collector who spreads their comics across five labeled boxes (attic-box-left, attic-box-right, living-room-shelf, office-binder, bank-vault for high-grade CGC) has no standard field to record that information. Yet knowing in two clicks where a copy physically sits is worth its weight in gold when you're hunting for a specific comic in a collection of 1,200 entries scattered everywhere. Second example: emotional provenance. Distinguishing comics you bought yourself from those received as gifts (from a grandfather, brother, partner, coworker) creates a distinct usage category. Nobody sells the comics their grandmother gave them, but they stay in the collection and have to remain identifiable.
Third example: pending transactions. "Sold but not yet shipped," "loaned to Maxime since March," "reserved for a trade with Nicolas," "awaiting CGC grading" are transitional statuses that don't fit the rigid modeling of standard filters. Fourth example: outside uses. A scholar preparing an article on the evolution of minority representation in 1970s comics wants to isolate the twenty comics they've annotated for their research. A collector running a weekly book club wants to filter the comics to read by next Sunday. These logics project an external intent onto the collection; there's no reason for the app's publisher to anticipate them. For an overview of the standard dimensions, see comic collection app features.
How tags work in My Comics Collection
You add a tag from a comic's detail page, in a dedicated section titled "🏷️ My tags." The field accepts keyboard input and triggers real-time autocomplete on tags already used elsewhere in the collection. If you've already created the tag "christmas-gift-2024" on three other comics, it shows up as a suggestion with its usage counter from the very first character you type. This autocomplete logic eliminates the accidental spelling variations ("christmas-gift," "Christmas-Gift," "christmas_gift," "christmas gift") that would needlessly fragment the filtering system. You confirm with the Enter key or a comma; the Backspace key on an empty field deletes the last tag added.
Each tag is stored as JSON in a dedicated column of the MySQL database, as one array of strings per comic. The normalization done server-side trims surrounding whitespace, caps each tag at thirty characters, and limits each comic to fifty tags. Deduplication is case-insensitive: "Attic-Box" and "attic-box" are treated as the same tag, and the first form encountered becomes the reference for display. This policy avoids the casing discrepancies that would undermine the consistency of the filtering system.
Filtering the collection by tags
Once you've placed a few tags, they automatically appear in a new sidebar section titled "🏷️ By Tag." Each tag is shown as a clickable chip with its occurrence counter. Clicking a tag activates the matching filter; clicking a second tag combines the two with AND logic (only comics carrying both tags are displayed). This cumulative logic is intentional: it lets you isolate, for instance, the comics tagged "to-reread AND loaned-julien" to quickly pull together the list to ask Julien for over your next coffee. A "✕ Clear all" button resets every active tag filter.
Tag filtering also applies during text searches: the search bar at the top of the interface now scans tag content in addition to the title, issue number, writer, and description. A collector who types "attic" into the bar instantly sees every comic tagged "attic-box-left," "attic-box-right," and "attic-blue-binder." This integration into the existing search engine spares you from switching between two interfaces. For complementary organizing methods, see organizing your comic collection.
Bulk application through the bulk-edit modal
The most powerful use of tags emerges when you combine them with multi-selection. The bulk-edit modal, accessible from the floating bar in selection mode, offers a dedicated "🏷️ Tags" field with three distinct operating modes. "Add" mode merges the tags you enter with the tags already present on each selected comic (automatic deduplication). "Replace" mode overwrites the existing tag list with the new list. "Remove" mode deletes the listed tags from the selected comics without touching the others.
In practice, relocating your physical collection comes down to filtering the view on the "attic-box-left" tag, selecting all, opening bulk-edit, Replace mode, and entering "truck-crate-1." Thirty seconds to reconfigure the traceability of three hundred copies. Without that combination, the operation would require three hundred individual page-opens. Prepping a book club where ten friends pass ten copies around: filter on "book-club-july," bulk-edit in Add mode with the tag "passed-to-julien," and every comic gets its new tag in one click. This mechanic turns tags from a static labeling system into a dynamic workflow tool.
Taxonomy best practices
The classic mistake with any open tagging system is creating too many near-identical variants that end up diluting the usefulness of filtering. Three simple rules prevent that slide. First rule: adopt a stable naming convention from the start. The most widespread practice in professional tagging systems (Notion, Roam Research, Obsidian) is to use lowercase consistently with hyphens, no accents or spaces. "christmas-gift-2024," not "Christmas Gift 2024." This early discipline avoids later fragmentation and makes tags easier to read on a narrow screen.
Second rule: favor the generic over the specific while the collection stays small. Tagging "gift" is enough for five comics you received as presents; refining into "christmas-gift," "birthday-gift," "wedding-gift" only becomes useful past fifteen entries per subcategory. Premature fine granularity bogs down data entry for a marginal filtering gain. Third rule: audit your tag system every six months. The sidebar's "By Tag" filter shows the occurrence counter; a tag with a single use is probably one to merge with a neighbor or delete. This twice-yearly audit keeps the system in a readable state.
Proven inspiration comes from English-language public libraries, which have used the LCSH system (Library of Congress Subject Headings) for comics since the 1990s: genre-superhero, era-bronze-age, theme-coming-of-age, setting-new-york. This multi-dimensional approach (genre × era × theme × setting) adapts naturally to personal tags. To structure a collection of a thousand comics and up along these lines, see our guide app for a large comic collection.
Competition and differentiation
In the comic-management app market, open tags remain rare. CLZ Comics (Netherlands, paid) has offered a tag system since 2019, but it's limited to five tags per comic and has no autocomplete on existing tags, which naturally fragments the taxonomy as you enter data. Key Collector (United States, free, English only) offers no user tag system at all, only predefined categories. League of Comic Geeks (United States, free, English) offers a thematic list system, but external to the comic's page — you have to create a list, then manually add each entry to it.
My Comics Collection positions itself as the app that delivers both the most permissive system (fifty tags per comic, smart autocomplete, multi-tag filtering with AND logic) and native integration into bulk-edit mode for power users. That combination is unique as of June 4, 2026. For collectors still on the fence with an Excel spreadsheet or Google Sheets — flexible tools, but with no autocomplete on values already entered — the article why a spreadsheet isn't enough lays out the relevant tipping points.
Frequently asked questions
Fifty tags per comic, each limited to thirty characters. Both bounds are enforced server-side on every save and stay well above real-world needs (the measured average among early adopters is four tags per comic). Past fifteen tags per entry, the page's readability degrades and the system becomes unmanageable. If you're approaching the fifty limit, it's probably a signal to clean up your taxonomy and merge tags that are too close.
Yes, completely. Tags are persisted in the MySQL database server-side, in the tags column of the user_comics table. They're reloaded on every login, so they're perfectly synced across computer, tablet, and smartphone. A tag added on a smartphone is immediately visible in the web version after syncing. No local browser storage is used: everything goes through the server, which guarantees consistency across all sessions.
The current CSV export includes the standard fields (title, issue number, condition, price, dates, statuses), but integrating custom tags into the CSV is planned for a later sprint. In the meantime, tags remain accessible through the collection's full JSON export if you need them for external use. For export methods, see the guide exporting your comic collection.
No, tags are strictly personal to each user. The tags one collector creates are visible only on their own collection; they don't show up in another user's autocomplete. This isolation is intentional, to preserve everyone's taxonomic freedom. If you share your collection via a public read-only link, the tags display in read mode but can't be edited by the visitor.
Yes. Tags are supported both on manually imported comics and on issues from the GCD catalog (210,000 Marvel and DC issues indexed). The storage mechanism is identical server-side: a tags column was added to the user_issues table alongside the one on user_comics, with silent auto-migration on the first login after deployment. No user action is required to enable this compatibility.
