X-ray powder diffraction data collected in transmission and high-throughput geometries were used to analyze form I of atorvastatin. The X-ray wavelength of the synchrotron radiation used in this study was determined to be λ=1.3771 Å. Form I of atorvastatin was found to be triclinic with space group P1 and unit cell parameters a=5.4568(2) Å, b=9.8887(4) Å, c=30.3091(9) Å, α=76.801(3)°, β=99.177(5)°, γ=105.318(5)°, V=1527.1(1) Å3, Z=1, and M=1209.41 g mol−1 Alternatively, another unit cell dimension can be used to describe the same P1 crystal with a=5.4564(2) Å, b=9.8883(4) Å, c=29.6555(8) Å, α=95.745(3)°, β=94.297(5)°, γ=105.327(5)°, and V=1526.8(1) Å3.

The internet provides access to a huge amount of information, and most people experience problems with information overload rather than scarcity. Glenda Browne explains how indexing provides a way of increasing retrieval of relevant information from the content available. Manual, book-style indexes can be created for websites and individual web documents such as online books. Keyword metadata is a crucial behind the scenes aid to improved search engine functioning, and categorisation, social bookmarking and automated indexing also play a part.

Derek Sturdy explains the importance of search engine optimisation for the legal information professional involved in the organisation's website in the Google era and suggests that the most important pieces of information are the title and the abstract. He also discusses the rise in automatic classification in the enterprise search context.
