Reference Managers and Proceedings: Zotero, Mendeley, EndNote and CSL

Reference managers store metadata and format it with a style. Proceedings papers break easily when the item type or the proceedings title is wrong, so check each imported record.

What a reference manager does

A reference manager is software that keeps a library of records and inserts formatted citations into your documents. The record holds fields such as authors, title, year, and the name of the proceedings. A style then decides how those fields are printed. If a field is empty or sits in the wrong place, the style cannot fix it.

This page describes Zotero, Mendeley and EndNote in general terms. Menu names change between versions, so use each product's current help for exact steps. We do not cover pricing or compare products.

Ways to import proceedings metadata

By identifier

Zotero's documentation says its Add Item by Identifier tool accepts an ISBN, DOI, PubMed ID, arXiv ID or ADS Bibcode, and fetches metadata from sources such as Crossref and arXiv. A DOI lookup works only if the publisher registered the paper with its own DOI and good metadata. See persistent identifiers.

From the browser

The Zotero Connector detects bibliographic data on a page and saves it, using a site-specific translator where one exists. On a page without a translator it may save only a Web Page item, which lacks the proceedings fields.

From files

BibTeX and RIS are the usual exchange formats. Mendeley documents import of both, and Zotero lists them as common formats for batch import. Export from a library or from DBLP, then import. Imported entries can arrive with the wrong type or a missing proceedings title, so inspect them.

Item type and proceedings title

The item type controls which fields exist. In Zotero, a Conference Paper has a Proceedings Title field, described as the title of the proceedings where the paper was published. It also has Conference Name, Publisher, Place, Pages and DOI fields. Zotero's documentation notes that for item types other than journal articles, a DOI may need to go in the Extra field.

A frequent problem is a paper imported as a Journal Article or Book Section. The style then prints the series or volume name as a journal. Change the item type, then check that the proceedings name moved into the right field. Zotero also suggests using Extra for a conference place when it differs from the publisher's place.

In EndNote, the help text lists conference name among the kinds of text that the Secondary Title field can hold. Confirm the field labels for your reference type in your own version.

CSL styles

CSL, the Citation Style Language, is an open XML-based format for describing citation and bibliography formatting. The CSL project says its repository holds over 10,000 free styles. Zotero's documentation says it uses CSL for all styles and lets you install more from its style repository or add your own .csl file. Mendeley's library guides say its styles also come from the CSL repository.

Two practical points follow. First, a style named after a university may differ from your department's rules. Second, style bugs exist. Zotero's documentation tells users to update Zotero and the style first, then report a mismatch in the forums. For Harvard variants see Harvard referencing for conference papers.

Common metadata errors

• Proceedings title missing or placed in the series field.
• Item type set to journal article.
• Event year used instead of the publication year, or the reverse.
• Editors missing, so the style cannot print in … (ed.).
• Title copied in all capitals, or with a trailing site name.
• Pages entered as an article number, or the other way round.
• A preprint record merged with the published paper.

The common mistakes page explains why several of these affect the final citation. When a record looks suspicious, compare it with the proceedings volume or the publisher page.

Cleaning duplicates

Zotero's duplicate detection compares title, DOI and ISBN. If those match or are missing, it also looks at years within one year of each other and at an author's last name and first initial. Open the Duplicate Items view, select a group, and merge; the merge keeps collections and tags. The documentation notes that detection works within one library only.

EndNote's default check compares reference type, author, year and title, and you can change the criteria in the preferences. Its help warns that records with different reference types may not be flagged, and library guides advise checking record numbers before deleting anything you have already cited in a document.

Merge carefully. A workshop paper and its later journal version share a title and authors but are different works, so do not merge them. See preprints and versions.

A safe workflow

1. Import by DOI or BibTeX.
2. Check the item type.
3. Compare title, authors, proceedings title, year and pages with the volume or publisher page.
4. Fill in editors if the style needs them.
5. Preview the citation in your chosen style.
6. Run the duplicate check before you write the final list.

Keep a short note of every manual correction you make, such as a changed item type or an added editor. If you re-import the same record later, the import may overwrite your fixes, and the note tells you what to restore. Before you submit, also export a copy of your library, so a sync error cannot remove your work.
