Docear4LibreOffice / Docear4OpenOffice: Call for Donation (2500$)

Published by Joeran Beel on

–> Read here for the latest update <–

One of our users’ most requested feature is an add-on for LibreOffice and OpenOffice, similar to Docear4Word, which allows adding formatted references and bibliographies in Microsoft Word based on Docear’s BibTeX files. Unfortunately, we have no skills in developing add-ons for Libre or OpenOffice, which is why we were looking for a freelancer to help us. Now, finally, we found one. The freelancer is offering to develop a pendant to Docear4Word that works with LibreOffice and OpenOffice. This means, you will be able to select a reference from Docears’ BibTeX database, and the add-on will insert the in-text citation and the bibliography in your Libre/OpenOffice document. Analog to Docear4Word, you will be able to choose from more than 2,000 citation styles to format your references.

However, the freelancer is not developing the add-on for free. He asks for 2500 US$ (~1,900€), which we believe to be a fair price. Therefore, we kindly ask you to donate, so we can pay the freelancer to develop a Docear4Libre/OpenOffice. Of course, the add-on will be open-source, reading not only Docear’s BibTeX files but also BibTeX files of other BibTeX based reference managers. The freelancer already developed a simple proof-of concept (see screenshot), which uses citeproc-java to add BibTeX based references. As such, we have no doubts that the freelancer will be able to deliver the promised add-on — if we can collect enough money.

The freelancer’s is already working on the add-on and his goal is to finish it in the next two months or so. However, as long as we cannot pay him, he will not release the add-on, even if he has finished his work (and if he learns that there are no donations coming, he might decide to stop his work at any time). Therefore, if you want a Docear4Libre/OpenOffice, please donate now! Donate 1$, 5$, 10$, 50$ or 500$ — any contribution matters, and the sooner we have all the money, the sooner you can manage your BibTeX references in LibreOffice and OpenOffice.

Donate via PayPal, or, to save PayPal fees, make a SEPA bank transfer to Docear, IBAN DE18700222000020015578, BIC FDDODEMMXXX. SEPA bank transfers are free of charge within the European Union.






We will keep you posted on the amount of donations, and any important news.

$1,405 donated – $1,095 are still missing!

Update 2014-07-14: In a previous version we wrote that ‘’ would match each donation, so we would only need $1,250 in donations. Unfortunately, the founder of experienced some trouble which made him withdraw his offer. This means, we need the full amount of $2,500. However, the freelancer who develops the add-on agreed to publish a first test version soon and this version should offer the most important features. We are still in discussion whether this version will be offered for free, or as shareware. However, if you have already donated, or donate before we publish the first test version, you definitely will get the version for free (and all future versions). We will keep you posted…

Update 2014-07-20: Although we collected less than half the money so far, the freelancer agreed to work on the add-on. We created three milestones, and as soon as the first milestone is reached, we will release a first alpha version of Docear4Libre/OpenOffice (and will pay $500 for it).

Update 2014-08-13: Sorry for the slow progress. The developer was ill for quite a while but now continues his work. We hope to release a first alpha version soon!

Update 2014-08-25: Only five more tickets to do before we release the first test version

How can I help with spreading the word for the donations necessary? I have help with a little, but see that we need more donations.
I can donate more, but my resources are limited.

    Joeran [Docear] · 26th May 2014 at 09:31

    That depends entirely upon you how to spread the word. If you have a Blog, write about it; If you have a twitter account, tweet about it; …

      Julian · 3rd February 2017 at 12:57

      That’s the biggest hoax.
      We will never see any plugin.

        Joeran [Docear] · 3rd February 2017 at 13:27

        It is true that the add-in will probably never be finished. However, at the top of this page is a link to further information where we communicate the problems very clearly and offer to pay all donations back.

will this work also for linux?

Dziga · 7th July 2014 at 12:16


What’s the situation about the crowdfunding for the libreoffice plugin ? (07/07/2014)
Thanks for your work !

Igor · 18th July 2014 at 22:57

It is a shame that the funding has been squeezed but this could still be feasible with extra 3-4 months (depending on the publicity). You may choose to release a video or screenshots first.

By the way, would the add-on support footnote-style citations as was suggested in the original task description?

Thanks again for your work!

    Joeran [Docear] · 21st July 2014 at 10:35

    I just updated the post – we hope that the first milestone will soon be reached and that there is a simple alpha version of the add-on. It is planned that it also creates references in footnotes.

valioni · 21st July 2014 at 20:46

it will take some time but with patience we’ll get there – all open source work flow

Gaetano Cajetan · 17th September 2014 at 13:39

Is there anyway you can put a bitcoin address so we can make our donations through that. Thanks! And how is the progress of the plugin going on? I just found out about this software and I am really excited to learn how to use it, and I see it as something that in the long run I can stick with as opposed to some of the other alternatives.

Anna · 7th October 2014 at 01:24

So what is the latest about the first alpha? Seems like the two remaining tickets are pending for over a month…

    Joeran [Docear] · 7th October 2014 at 19:55

    i am sorry for the delays. the developer (again) faced some private problems but he ensured me that we could expect an alpha before november. in case that the work should take longer, i will also consider to look for another freelancer who continues the job (or at least supports the current developer).

eyeore · 27th February 2015 at 12:49

Is this project still going on? I am very interested in it (as I don’t run word on my computer). I would like to help with croudfunding, etc. if this is still a viable project.

Christopher R. Lee · 28th August 2016 at 13:25

I came across this page even before downloading Docear, as I use LO for stuff that is not too serious.

For any document that has numerous legends, references and cross references I would very strongly recommend people try to learn LaTeX, specially if your institution has a LaTeX guru or you can get a template that covers your basic requirements. It dates from 1977 and won’t be going away anytime soon.

The biggest advantage is that every reference is marked up with a key in plain text that you can make yourself: for example ref{fig:mypicture} cite{lee1977b}. I don’t like the way LO does legends and in my clumsy hands cross-referencing can become irretrievably corrupted; with LaTeX everything is clear and visible.

You also get a level of typographically perfect automation that is not available with word processors.

I’m old and geek enough not to be bothered by the coding, but Henrik Just has written an extension Writer2LaTeX (also usable as stand-alone) that lets you use LO as a front-end to LaTeX:
