A guide to calendar collections
A calendar collection can answer several different questions. A manuscript may preserve the arrangement of an earlier calendar. A printed sheet may document an advertiser, a local printer or the way two dating systems shared a page. An annotated copy may tell us something about its owner. The most useful starting point is therefore a question about an object, followed by a record that identifies the particular surviving copy.
Keep three things together as you research: the institution’s catalogue record, an image of the whole object, and any scholarship used to interpret it. They do different jobs. The record identifies the item, the image supplies visible details, and scholarship helps explain its historical context.
Finding calendar objects
Manuscripts and fragments. Search by shelfmark when one is known. A shelfmark is the identifier used to locate an item in a library collection. Copy it exactly, including punctuation. For broader discovery, try “calendar,” “almanac,” a named calendar maker or the subject categories attached to a relevant record. A fragment may be catalogued under a larger manuscript or collection, so note whether the description covers the whole item or only its calendar material.
Printed books and albums. A bound calendar book, an individual print and an album assembled from loose prints need different descriptions. For an album, record both the compilation and the particular leaf being studied. Compare calendars from different countries as distinct publications: related formats do not imply identical month numbering, date rules or observances.
Wall calendars and advertising sheets. Search by advertiser, printer, place and year as well as by object type. A calendar may appear among advertisements, posters or other short-lived printed materials. Names printed in Chinese and historical English trade names can provide different search terms. Record both when they appear on the object.

| French School of Asian Studies archives | Advertising prints with detailed archival descriptions | Calendar poster, reference FR EFEO IC002/G/3 | A shared design and the condition of each surviving copy |
The catalogue record
A reliable working description identifies a particular object rather than merely naming a design. “Chinese calendar, 1930s” is a discovery label. An institution, reference number, title, date qualification and physical description make that label useful to another researcher.
The following fields help describe a calendar object.
| Field | What to record | Why it matters |
|---|---|---|
| Institution and identifier | Repository, collection, accession number or shelfmark | Identifies the surviving copy, even when titles are similar |
| Title and object type | Catalogue title, printed title and terms such as calendar, almanac or advertisement | Preserves the difference between a catalogue description and wording on the object |
| Dates | Production date, dates covered, inscriptions and acquisition date | Prevents unrelated dates from collapsing into one year |
| People and businesses | Artist, compiler, printer, publisher, advertiser and distributor, with their stated roles | A prominent company name does not automatically identify the printer |
| Place | Production place, find site and later collecting locations | These describe different stages of the object’s history |
| Material and format | Paper, printing process, dimensions, mounting and surviving leaves | Helps distinguish an original sheet, an album leaf and a later reproduction |
| Condition and annotations | Missing areas, repairs, handwriting and signs of reuse | Separates the publication’s design from this copy’s later history |
| Documentation and image rights | Stable record address, supporting publications, image credit and reuse statement | Keeps the research traceable and records the conditions for using an illustration |
Dates on the object and in the record
A calendar can carry several dates: the year it covers, a printing date, an owner’s dated inscription and the date when it entered a collection. Enter these separately, noting where each appears and what it describes. A calendar intended for the coming year may have been printed during the preceding year.
A modern reproduction can also carry an old calendar date. The printed year identifies the calendar represented, but does not by itself date the paper now in front of you. Likewise, an approximate attribution remains approximate: retain “about,” “probably,” a date range or a question mark when those qualifications occur in the record.
For a date using a reign year or Ganzhi, the stem-and-branch cycle, transcribe the original before adding a conversion. Keep the lunar month and day, including any leap-month label, and record the reference used to interpret the date. This preserves the original information if the conversion later needs revision.
Designs and surviving copies
A design can survive in several copies with different mounting, annotations, repairs or missing areas. Describe those features for the copy being studied. When comparing copies, distinguish changes in the printed design from changes made after printing. Handwritten notes, a later album mount and a different printed advertiser’s name belong to different parts of that history.
Working with images
Begin with a whole-object view. Then examine the date panel, the margins, the imprint and any reverse image. A crop containing only the central portrait can remove the calendar’s year and commercial identity. A crop containing only a manuscript’s date columns can remove a heading or a colophon, the closing note that may identify its maker or date. Keep each detail image linked to the whole object in your notes.
Distinguish printed text from handwritten additions. A note may be visible even when its author or date is unknown. When an image is too small to resolve a character, mark the reading as uncertain rather than completing it from an expected formula.
For a working illustration set, retain an uncropped reference image and make separate labelled details. Record whether an illustration shows the front, reverse, a particular leaf or only a portion of the object. Avoid silently removing tears, stains or later notes from an image intended as historical evidence. These are part of the copy being discussed, even when they obscure its original design.
Image availability and reuse permission are separate matters. The catalogue text, the photograph and the object depicted may have different reuse conditions. Consult the statement attached to the actual image, retain its credit line and obtain any required permission before publication.
