Keeping track of and organizing our research materials can be overwhelming. Genealogists use a wide variety of sources and reference tools to discover and dig deeper into our family history: historical records, books and periodicals, photos, maps, videos, articles and web pages, reports, databases, digital archives, etc. Zotero is a free research and citation management system heavily used in academia, but it can also be extremely valuable for genealogists whether for their family history research, or for professional publishing and presentations. It is available for both Mac and PC users. Zotero can integrate well with your existing research workflow and organization tools such Dropbox, Google Drive, and Evernote. What it excels at is letting you apply the same source item and notes to multiple people, families, and projects without having to duplicate those in multiple folders or notebooks.
