Your library

Your library holds every source you have cited or saved in Papero. You do not have to add papers to it by hand: each paper you cite, each paper you save from a search, each custom citation and each import goes there. A PDF you upload joins the source it belongs to, or becomes a new source.

Papero keeps one source per paper. When you cite, save or import a paper that is already in your library, such as one with the same DOI, Papero uses the source you have instead of making a copy.

Open the Library page

1. In the sidebar, press Library.
2. The page lists your sources, the most recently changed first, with how many there are at the top.

Each row shows the title, the authors, the year and journal, and where the source is cited, such as Not cited in any document. A row also shows the collections the source is in and, when the source has a PDF, a badge with its page count. A long library shows part of the list at a time: press Load more to see the rest.

The box above the list searches your library: type part of a title, an author, a journal or a year.

Next to the heading, Import brings in sources from a file, Zotero, Mendeley or the web, and Export saves your library as a file on Plus. See Import BibTeX and RIS files.

Sort sources into collections

Collections are folders for your sources, such as one per chapter or project. A source can be in several collections, and a collection only groups sources: the sources themselves stay in your library.

To make a collection:

1. Under Collections on the left, press New collection.
2. Type a name in Collection name.
3. Press Create.

To put a source in a collection:

1. Point at the source's row. Its buttons show on the right (on a touch screen they always show).
2. Press the collections button. Its tip says Collections for and the source's title.
3. Under Add to collection, tick each collection the source belongs in. Untick one to take the source out.

Click a collection on the left to see only its sources, and All sources to see them all again. To rename or delete a collection, press its More for button, then Rename or Delete. Deleting asks you once more; press Delete collection to go ahead. The sources in it stay in your library.

You can also add a paper to a collection from the Find papers page, and put a whole import into one. There is a limit on how many collections you can keep, and Papero says so when you reach it.

Edit or delete a source

The pencil button on a row opens the source in the Edit source drawer. There you can correct its details and add, open or remove its PDF. See Custom citations.

To delete a source, press the bin button on its row, then Yes, delete. Papero does not delete a source that a document still cites, archived documents included. It tells you how many documents cite it, so you can remove those citations first. Deleting a source also deletes its PDF.

The Library panel in a document

While you write, you can reach your library without leaving the document.

1. Press Side panel at the top right of the document.
2. Choose the Library tab.

You can also choose Library panel in the command palette. At the top of the panel:

• All sources or In this document chooses which sources to list.
• A search box finds sources by title, author, journal or year.
• All collections narrows the list to one collection, once you have some.
• Any, Has PDF and No PDF filter by whether a source has a PDF.

Each source in the panel has these buttons:

• Cite puts a citation of the source at your cursor. Click in your text first, or Papero says Click in your text first, then cite.
• Open PDF opens its PDF in the reader beside your text. See The PDF reader.
• Add PDF and Get free PDF add a PDF to a source that has none. See Upload PDFs and Get a free PDF.
• Details opens the source's details.

A source the document already cites says Cited here. When some papers this document cites have no PDF, a line above the list says how many. Press Review next to it to list them. Web pages, books and datasets are left out of that count. You can also drop PDFs into the panel.

Free and Plus

Free and Plus have the same library: you can read, search, edit and delete your sources, sort them into collections, import and add PDFs. You cite them from the Library panel or the Library tab in Cite. Exporting your sources as a file is part of Plus. To compare the plans, see pricing.

Next: import BibTeX and RIS files.
