Pre‐ and postpilot identifiability. Resources (primary antibodies, organisms, and tools) were considered identifiable if they contained an accurate RRID or by using the same criteria as described in (Vasilevsky et al. 2013). For tools (software and databases, which were not previously analyzed), these resources were considered identifiable if they contained an RRID or reported the manufacturer and version number. The total number of resources for each type is: primary antibodies prepilot, n = 140; primary antibodies postpilot, n = 465; organisms prepilot, n = 58; organisms postpilot, n = 139; noncommercial tools prepilot, n = 59; noncommercial tools postpilot, n = 101. The y‐axis is the average percent identifiable for each resource type. Variation from this average is shown by the bars: error bars indicate upper and lower 95% confidence intervals. Asterisks indicate significant difference by a z‐score greater than 1.96.
