Can I have a larger RefWorks database?
Your local RefWorks administrator sets the default size for accounts at your institution, and can expand your account size at their discretion.
It is important to note that having a large database with many attachments will make it very difficult, if not impossible, to back-up or move your account. You will be able to back-up or move your citations, but moving attachments may not be possible in accounts larger than 1 GB.
