Hi Manuela, Unfortunately, offhand, Google Scholar may have the best answer to this question (as they may be able to point at exactly what is wrong in your scenario). But there are a few things you probably should be aware of that could help you debug this issue yourself as well:
(1) Newer versions of DSpace (4.0 or above) have additional Google Scholar Search Engine Optimization enhancements. Specifically for 4.0, we talked directly with the Google Scholar team about common problems they have had in indexing DSpace, and we worked to resolve them. So, it's very possible that you will immediately see better Google Scholar inclusion overall simply by upgrading DSpace. For more information see: https://wiki.duraspace.org/display/DSDOC4x/Search+Engine+Optimization (2) @Mire (a service provider for DSpace) has also developed a tool which specifically analyzes DSpace sites for possible misconfiguration (which may affect how well Google Scholar can index your site). That new tool is provided here: https://atmire.com/website/?q=content/free-tool-dspace-seo-analysis Hopefully that helps. But, obviously let us know if you have further followup questions, etc. - Tim On 7/21/2014 12:49 PM, Manuela Klanovicz Ferreira wrote: > My repository uses DSpace 1.8.1 (www.lume.ufrgs.br > <http://www.lume.ufrgs.br>) > > When I searched "site:lume.ufrgs.br" at Google Scholar, 33,900 articles > were returned, almost all with PDF link on the right.
