Recent edit to Barcode
Hello, and welcome to Wikipedia. I noticed that you made a change to an article, Barcode, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you!

Please do not add original research or novel syntheses of published material to articles as you apparently did to Barcode. Please cite a reliable source for all of your contributions. For a Wikipedia article to write that somebody was "one of the first persons to be involved in developing the Bar Code System", it would require a secondary source that stated this, not a primary source patent which you personally feel qualifies the statement.

Please stop adding unsourced content, as you did to Barcode. This contravenes Wikipedia's policy on verifiability. If you continue to do so, you may be blocked from editing Wikipedia.

Yes, even a statement like "received 3 patents on the Bar Code" needs a secondary source: per WP:PRIMARY, "All interpretive claims, analyses, or synthetic claims about primary sources must be referenced to a secondary source, rather than to an original analysis of the primary-source material by Wikipedia editors." - you are personally deciding that the patents are using "bar code" in the same sense as the main article, and that Murthy is worth mentioning here but the other names on the patents aren't. If Murthy's contribution was recognised as significant, it should be easy to find references to it in textbooks on the subject, and use those as sources. If Murthy's work was less significant or has not yet been recognised, it is not appropriate for an encyclopedia entry on barcodes. --McGeddon (talk) 09:45, 27 December 2014 (UTC)
