There is no fixed time for the retrieval of ei conference papers, which is related to the conference organizers. Generally speaking, authoritative ei meetings are searched 1-3 months after the meeting, general ei meetings are searched 4-6 months after the meeting, and some non-authoritative meetings have not been searched or searched for more than one year. If the publishing house is well-known such as IEEE, TTP, WIT, etc., it can basically guarantee the retrieval, but no one can guarantee the retrieval time. For example, an author published a conference paper in March last year, held a meeting in July and August, and only retrieved it in April this year. For example, another author started his business in 65438+February last year and searched in May this year. According to the general situation, ei conference papers can be retrieved about 3-9 months after the meeting, but the possibility of not retrieving them or waiting for a longer time is not ruled out.
