|Library is a collection of information, books, journal, videos, cds and DVDs. They can include information related to any topic. That can be in any described form. Sometimes libraries may be specific to a particular topic. Next generation sequencing libraries include all the information and materials related to next generation sequencing.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
