• A neutron & X-ray scattering length density database being developed by ORSO
• Other NIST tools on the web
• Manfred Kriechbaum's scattering simulations and animations
• Andrej Sali's Fast Online saXS (FoXS) curve calculator
• A series of tools for X-ray anomalous scattering resources (primarily for crystallography) are available from this site
• A peptide property calculator which can calculate amino acid volumes is available from Northwestern University
• An online protein neutron scattering length density calculator is available from ISIS 
• MULCH: ModULes For The Analysis Of Contrast Variation Data, is a powerful set of modules for use in calculating protein scattering contrasts for SANS
• Steen Hansen's BayesApp tools for calculating scattering, structure factors, and distance distribution functions
• Andreas Larsen's web tutorials on small-angle scattering using Shape2SAS and SasView

BLOGS MAILING LISTS AND FORUMS

• The IUCr maintains the main moderated and archived SAS mailing list at  http://mailman.iucr.org/pipermail/sa_scat (with a pre-2002 archive here). SAS practitioners are strongly encouraged to subscribe to this list (and indeed the IUCr do view the number of subscribers and posts as an indication of the health of the SAS community).
• Brian Pauw's weblog about his experiences as a practitioner of small-angle scattering.
• The ATSAS developers at EMBL host some forums particularly relevant to biological small angle scattering.

STANDARDS

• The CanSAS-NeXus NXcanSAS HDF5 nD reduced data format
• The CanSAS SASXML 1D reduced data format
  • A web form for converting 3-column ASCII CSV (eg, Q, I(Q), Ierror) data into the CanSAS SASXML 1D format

PROTOCOLS

• General SAXS-Based Screening Protocol for Studying Physical Stability of Protein Formulations
  • Analysis template and automation script (ZIP file download)

FORM FACTORS

• A compilation of references to scattering form factors compiled by Adrian Rennie.
• A link to the SasView fitting model documentation.

BIBLIOGRAPHIES

• A fairly extensive bibliography (leaning more towards SANS at present) has been compiled by Stephen King, Ron Ghosh  & Adrian Rennie.
• "Small Angle X-ray Scattering" (eds. O. Glatter & O. Kratky) is a fairly comprehensive text available for legal download as a pdf.
• Online, open-access, archive of Fibre Diffraction Review (1992-2006)
• The famous data booklets -  the Orange book for X-rays and the Blue book for neutrons - are available as downloadable pdfs on the web. Instructions for obtaining hard copies are available at each site.
