Reference numbering collating references

Collate all references at the end of the manuscript in numerical order if cited by number and in alphabetical order if cited by author. Do not include items in the reference list that are not cited in the manuscript. Check the publication for which you are writing. Some publications do not allow multiple references to be listed as one numbered entry they prefer that each numbered entry include only one unique reference. 

A selection of observations taken from a number of different FDA Warning Letters issued in 2001 that reference software is provided below. It is not a comprehensive listing but rather it has been collated in support of the validation approach proposed by this case study. 

First of all, we need to clarify some definitions. With the collapse of communism in Eastern Europe and the Soviet Union and the opening up of China, there is a clear need now to look at developments in the lead and zinc industries in global terms i.e., including every country in the world. However, in looking at historic development trends, one encounters the problem of consistency and accuracy of reporting in the former communist countries, particularly the Soviet Union, as well as continuing problems in the collection and collation of data in some of these countries and in China. For this reason, we continue to make the distinction between the transitional economies, which we define as China, North Korea, Vietnam, Cuba, the Former Soviet Union (FSU) and the Warsaw Pact countries of Eastern Europe, and the Western World which comprises all other countries. Much of the subsequent discussion refers solely to the Western World but, where possible, we also quote global numbers and/or numbers for the transitional economies.
